ab79d6e2 | 2013-11-21 06:12:35 | This separates the 32-bit sysv/linux/bsd code from the 64-bit linux code, and makes it possible to link code compiled with different options to those used to compile libffi. For example, a -mlong-double-128 libffi can be used with -mlong-double-64 code. Using the return value area as a place to pass parameters wasn't such a good idea, causing a failure of cls_ulonglong.c. I didn't see this when running the mainline gcc libffi testsuite because that version of the test is inferior to the upstreamm libffi test. Using NUM_FPR_ARG_REGISTERS rather than NUM_FPR_ARG_REGISTERS64 meant that a parameter save area could be allocated before it was strictly necessary. Wrong but harmless. Found when splitting apart ffi.c into 32-bit and 64-bit support. | |

83f65b63 | 2013-11-16 06:53:50 | Finally, this adds _CALL_ELF == 2 support. ELFv1 objects can't be linked with ELFv2 objects, so this is one case where preprocessor tests in ffi.c are fine. Also, there is no need to define a new FFI_ELFv2 or somesuch value in enum ffi_abi. FFI_LINUX64 will happily serve both ABIs. | |

36285137 | 2013-11-16 06:52:43 | Andreas' 2013-02-08 change reverted some breakage for struct return values from 2011-11-12, but in so doing reintroduced string instructions to sysv.S that are not supported on all powerpc variants. This patch properly copies the bounce buffer to destination in C code rather than in asm. I have tested this on powerpc64-linux, powerpc-linux and powerpc-freebsd. Well, the last on powerpc-linux by lying to configure with CC="gcc -m32 -msvr4-struct-return -mlong-double-64" \ CXX="g++ -m32 -msvr4-struct-return -mlong-double-64" \ /src/libffi-current/configure --build=powerpc-freebsd and then make && make CC="gcc -m32" CXX="g++ -m32" \ RUNTESTFLAGS=--target_board=unix/-m32/-msvr4-struct-return/-mlong-double-64\ check | |

1c06515d | 2013-11-16 06:41:36 | The powerpc64 ABIs align structs passed by value, a fact ignored by gcc for quite some time. Since gcc now does the correct alignment, libffi needs to follow suit. This ought to be made selectable via a new abi value, and the #ifdefs removed from ffi.c along with many other #ifdefs present there and in assembly. I'll do that with a followup patch sometime. This is a revised version of https://sourceware.org/ml/libffi-discuss/2013/msg00162.html | |

164283f4 | 2013-11-16 06:38:55 | The powerpc64 support opted to pass floating point values both in the fpr area and the parameter save area, necessary when the backend doesn't know if a function argument corresponds to the ellipsis arguments of a variadic function. This patch adds powerpc support for variadic functions, and changes the code to only pass fp in the ABI mandated area. ELFv2 needs this change since the parameter save area may not exist there. This also fixes two faulty tests that used a non-variadic function cast to call a variadic function, and spuriously reasoned that this is somehow necessary for static functions.. | |
